EXTING'UISHER.

Application filed October 14, 1922, Serial No 594,661. Renewed December 17, 1924.

To all whom it may concern:

Be it known that we, VVILUAM L. JOHN- SON and JAMES M. Hnmus, J12, citizens of the United States, residing at Detroit, in

the county of Vi ayne and State of lVfichigan,

have invented new and useful Improvements in Extinguishers, of which. the following is a specification.

This invention has for its object, the provision of a safety gas appliance, designed for use with the valve to effectively and positively close the valve, and therebyeliminate any possible escape of gas which may be caused by one neglecting to properly close the valve.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings,

the invention residing in the construction,

combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indi cate similar parts in the several views, and wherein?- Figure 1 is a view in elevation showing the appliance associated with a gas fixture and the parts in normal position.

Figure 2 is a view taken at a right angle to Figure 1.

Figure 3 is a view, showing the position of the parts when the valve is opened.

Figure 4: is a fragmentary detailed view of the appliance.

The appliance forming the subject matter of the present invention embodies spaced hook-like members 10 which are adapted to engage the gas pipe 11 to assist in supporting the appliance in condition for use. The

hoolelike members support an arcuateshaped wire frame, the body portion of which is indicated at 11', and which frame includes radially disposed members 12 which have their corresponding inner extremities closely related and connected together by means of a resilient clamp 13. The radially disposed members 12 project beyond the arcuate-shaped member 11' and have their extremities curved in the same direction as as at 14 for a purpose to be hereinafter described. 7

Depending from the arcuate-shaped mem ber 11 are diagonally disposed coiled springs 15 which support an elongated frame-like member 16, the frame-like member being disposed to receive the key of the valve indicated at 17. The springs normally maintain the frame in the position shown in Figure 1, and as the frame receives the key of the valve it is obvious that the valve is held effectively closed under normal conditions. When it is desired to open the valve, it is necessary to turn the frame to the position shown in Figure 3 which of course places the springs under tension. The frame is turned to this position by means of a manipulating rod 19 which slides in loops 20 carried by the frame. The rod is frictionally engaged by the loops 20 to hold it in any given position, it being understood that the rod is susceptible of vertical adjustment toward and away from the curved extremities 14 of the radially disposed members 12. When the valve is opened, the rod 19 is positioned to engage one of the curved extremities 14 of the members 12, and in this manner, the frame and the valve are held in the position illustrated in Figure 3. When the rod 19 is moved downwardly out of engagement from the curved extremity of the particular member 12 and subsequently released, the springs function to return the frame 18 to normal position and incidentally close the valve. By reason of the construction and arrangement of parts shown and described, itis manifest that the appliance will effectively move the valve to its. closed position and thereby eliminate any possible escape of gas which may be caused by a person neglecting to fully turn off the valve.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, we desire to have it understood that we do not limit ourselves to what is herein shown and described, and that such changes may be resorted to when desired as fall Within the scope of what is claimed.

What we claim is 1. A safety appliance for valves of the character described, comprising a framelike member arranged to receive the key of the valve, means for supporting the frame-like member in position for use, said means including crossed resilient elements connected with the frame, and adapted to be placed under tension when the frame is turned to open the valve, a manipulating rod slidably supported by the frame-like member and designed to engage said supporting means in a manner to hold the I of the valve, a supporting structure for said frame, said structure including an arcuate-shaped member, a resilient clamp, radially disposed members terminally connected with the clamp and said arcuatcshaped member and having curved extremities projecting beyond the latter, and crossed resilient elements depending from said arcuate-shaped member and terminally connected With the frame, and a manipulating element carried by the frame and utilized to turn the latter to open the valve against the tenslon of sald resilient elements, and

7 said manipulating element being adjustable andiadapted to be moved into engagement with the curved extremities of the radially disposed member to hold the valve opened against the tension of the resilient elements.

3. A safety gas appliance of the character described including spaced hook-like supporting elements, an arcuate-sha )ed member terminally connected with sai elements, a resilient clamp arranged between said elements, radially disposed members projecting from said clamp and connected with the arcuate-shaped member, said radially disposed members projecting beyond the arcuate-shaped members and extended to pro vide curved extremities, a frame-like member adapted to receive the key of the valve, crossed resilient elements connected with the arcuate shaped member and suspending said frame therefrom, and a manipulating rod slidably supported by the frame-like member and adapted to cooperate with the curved extremities of the radially disposed members as and for the purpose specified.

In testimony whereof we afiix our signatures.
